If you have a question about a plant or need help with treating exposure to what you think is a poisonous plant, call the UC Irvine Regional Poison Center at (714) 634-5988 or (800) 544-4404. Because it is difficult to furnish names of all plants from a telephone conversation, the center recommends making a list of all the plants you do not know that are in your yard or home and take them to a nursery so they can be identified.
